Abstract

This encoding device (100) comprises a circuit (160) and a memory (162). In a case where the circuit (160), using the memory (162), encodes a subject block in an inter-prediction mode for performing a motion search in a decoding device (merge mode in S201), the circuit: derives a first motion vector of the subject block (S203); stores the derived first motion vector in the memory (162); derives a second motion vector of the subject block (S204); generates a predicted image of the subject block by motion compensation using the second motion vector (S208); and in the first motion vector derivation, uses the first motion vector of a processed block to derive the first motion vector of the subject block.
